A deformation processing support system acquires target shape data of a work having a reference line; acquires intermediate shape data from the work in an intermediate shape having a reference line marked thereon; and overlaps the two data on each other by aligning the reference lines relative to each other, to calculate a necessary deformation amount of the work based on a difference between the two data overlapped on each other. To align the reference lines with each other, first and second alignment axes with the same length calculated for the respective reference lines are superimposed on each other. Subsequently, the intermediate shape data is relatively rotated with respect to the target shape data around the first alignment axis.

The present invention relates to a linear motion guide unit manufactured at low cost by forming at least a slider from a single metal plate, and reduced in sliding resistance of rolling elements as well as a method of manufacturing the same. The linear motion guide unit includes a guide rail, and the slider formed from a single metal plate. The guide rail has a bottom part, and a pair of longitudinal side parts standing from opposite sides of the bottom part, extending longitudinally in a mutually facing manner, and having respective raceway grooves in which the rolling elements roll. The slider includes an upper part, a pair of mutually facing sleeve parts extending downward from opposite sides of the upper part and having respective raceway grooves and return passages, and end cap parts formed respectively at opposite ends of the upper part and having turnaround grooves.

In certain embodiments described herein, a heated line forming system includes a heating coil system configured to produce a heated line on a surface of a metal part. The heated line forming system also includes an air knife cooling system configured to maintain a dry area for the heated line, and to direct a coolant (e.g., cooling water, liquified gases such as liquid argon, solidified gases such as carbon dioxide snow, and so forth) around the heated line via a spray mechanism such that the coolant does not flow or splash into the heated line on the metal part. In certain embodiments, the heated line forming system includes multiple induction coils arranged along a line and spaced a short distance apart, but which, when operated simultaneously together, form a heated line on a surface of a metal part.

A workpiece material is fed between rollers to bend the workpiece material while rolling, wherein the workpiece has a first thickness portion and a second thickness portion connected to each other with a setting angle of 90 degrees. The first thickness portion increases from an inner side toward an outer side, and a thickness on an outer peripheral side of the first thickness portion is M, and a thickness of a cross section of the second thickness portion is N. The workpiece material is rolled in such that at a completion of bending, a thickness of a cross section of a first thickness portion is m, an outer radius of the first thickness portion is R, an inner radius of the first thickness portion is r, and a thickness of a cross section of a second thickness portion is n, and M equals to m(R/r), and N equals to n(R/r).

A mobile machine tool includes a main body, a machine bed head, and an end effector. The main body permits the machine tool to stand on the ground. The machine bed head is cantilevered relative to the main body. The end effector is guided on the machine bed head by a positioning system. The machine bed head is attached to the main body by a mechanically overdetermined frame.

The present invention belongs to the technical field of high-efficiency, high-precision and high-performance laser bending of metal sheets, and relates to a line-shape spot laser bending method for metal sheets. The present invention uses a multimode laser scanning mirror or a single piezoelectric deformable mirror to convert laser Gaussian distributed point spots to uniformly distributed line-shape spot, and meanwhile, loads the spots in a bending line area and bends metal sheets so that the temperature field in the bending line of the metal sheet is distributed uniformly to achieve the purposes of reducing warpage deformation, enhancing bending angle consistency and increasing the bending efficiency.
